Semolina (1887 – 1909) was a British Thoroughbred racehorse and broodmare. Bred and owned by the 6th Duke of Portland, she was one of the best two-year-olds in England in 1889 when she won thirteen times from fifteen races. In the following spring she recorded her biggest success when she won the 1000 Guineas. She went on to run fourth in the Oaks Stakes and third in the Coronation Stakes, but never won again and was retired from racing at the end of the year. She had modest success as a dam of winners.
